Michael G., in the modern world, more and more people are increasingly experiencing the negative effects of the external environment?
Michael Leizerman: unfortunately. One of the organs exposed to massive negative impacts, – the organ of hearing. The ear has evolved for centuries. From superstroke perception of the sounds from our ancestors of monkeys to moderate the sharpness of perception, which is essential to man in his daily life, not related to danger and every moment of life.
Academician Elena Golukhova: Safety and effectiveness – the goal of our work
it is believed that the human ear perceives sounds with frequencies from 20 to 20,000 Hertz. And many animals are able to catch and infrasound – below 20 Hz and ultrasound above 20,000 Hz. This allows them to survive in an unpredictable, from a human point of view, circumstances. And we often lose the ability to perceive even that relatively small part of the sounds which we have inherited from nature.
Which reduces the range of sounds perceived by the human ear?
Michael Leizerman: first, the external noise that accompanies our lives: motors, sharp horns, loud music. Secondly, diseases accompanied by changes in vascular tone, nourishes all parts of the auditory analyzer. From the inner ear, where its main organ, called the cochlea, its delicate hairs starts the process of transmission of sound waves along nerve pathways to the cerebral cortex. And up to the cortex, which is able to analyze and distinguish all the shades of sounds in the external environment. And such mass diseases: hypertension, atherosclerosis, diabetes and many others. Thirdly, is any intoxication: alcohol, nicotine, viral infection.
the Noise in the ear? Reducing the intelligibility of the interlocutor? Pain at loud sounds? Do not pull on time, contact your audiologist
Stop! You mentioned viral infections. Coronavirus will cause damage to our ears?
Michael Leizerman: no Such data. Another thing that is not reset with boards drug exposure, assigned in different situations to treat certain diseases: toxic antibiotics, diuretics, large doses of hormones, products for cancer chemotherapy, and so on. And if in this list there are diseases that do not depend on our lifestyle and habits, the constant sound from the headphones with the young people belongs to bad habits, get rid of them in our power.
I’m not talking about boys and girls crossing the road in the trendy hoods that limit their peripheral vision. Almost every earphone that complement the complete lack of ability to react to unusual and disturbing sound. For example, the whistle of the brakes of the car or motorcycle. So, listening to music or the news, or raising the level of your English, you can be in trauma or even worse, in the morgue.
by the Way, it is proved that the constant noise pollution on the ears for more than two hours a day negatively impacts on thresholds for the perception of sounds, gradually leading to hearing loss. It is often the beginning process of hearing loss is difficult to stop. In our Department constantly treated dozens of patients who lost hearing as a result of one or several of the above reasons. And in social terms, in the life of deafness gives less discomfort and experiences than blindness or absence of feet or hands.
the Eternal question: what to do? Your professional advice.
Michael Leizerman: They are essentially banal, but effective. You need to reduce the number of adverse effects on the auditory organ, limit timethe water habits. But at the first sign of the disease: the noise in the ear, reducing the intelligibility of the interlocutor, pain in the ears at loud sounds… Not pull on time, contact your audiologist. Maybe it’s not too late!
And what about those who have hearing loss occurred long ago?
Academician David Ioseliani: Treatment without rehabilitation – a waste of money
Michael Leizerman: They also should be referred to a specialist, audiologist or otolaryngologist. Many of them we can help. It is pertinent to recall that often we are dealing with those who carelessly cleaned the ears with cotton sticks and injured the eardrum. These sticks really are cosmetic and have nothing to do with cleaning the ear canal. In some countries they are banned and no longer available.
Earlier, when the ears are cleaned with a regular match with fleece, these troubles were considerably less. In the case of injury of the tympanic membrane cosmetic cotton swab causes a sharp pain, a sharp decrease in hearing, sometimes discharge of blood from the ear canal. If this happens, do not pull, go to the doctor. The ear examination under the microscope will reveal the location of the perforation and to take the necessary efforts to it promptly closed, and the hearing was restored. If this is not done, it is likely to chronic suppurative otitis media, which is difficult to cure.
a Lot of people who have hearing problems, were not examined and were not treated.
Michael Leizerman: to Hide your head in the sand is not the best option. In some cases, hearing can be restored. For example, in chronic otitis media there are slugbottomoffset operation. When otosclerosis ear is also possible to operate and achieve quite satisfying anorytelling the level of perception of sounds.
If a person suffers from chronic sensorineural hearing loss, which was previously called “cochlear neuritis”, then it is output as the selection of a hearing aid. Modern devices are different from those worn in the breast pocket, which squeaked and gave a quality of hearing. They were replaced by miniature digital cameras that can be hidden in the ear canal. They are not visible to the uninitiated others, and the level of audibility is quite comfortable.
a talk about the fact that wearing hearing AIDS is killing the already faulty perception of sounds?
Michael Leizerman: Discussions, and more! After all, conventional to wear glasses when vision. Exactly the same shows a hearing aid with hearing loss.
